Specification of Letters Patent.

Patented Dec. 6, 1910.

To all whom it may concern.

Be it known that I, ALVIN FLAVEL NIMs, a citizen of the United States,and a resident of Philadelphia, in the county of Jefferson and State ofNew York, have invented a new and Improved Mixing-Machine, of which thefollowing is a full, clear, and exact description.

This invention relates to machines for mixing concrete and similarmaterial, and relates more particularly to a mixing machine comprisinghollow, communicating sections arranged so that they can be revolved,and having an inlet and an out-let, partitions being provided within thesections, which serve to direct the material passing through the same.

An object of the invention is to provide a simple, strong and efficientmachine of the class described, in which concrete or other material canbe thoroughly mixed, which can be operated continuously orintermittently, which is so constructed that none of the material canescape accidentally, and which is further so constructed that it isimpossible for quantities of the material to collect and remain at anypoint of the machine.

A further object of the invention is to provide a machine of the classdescribed in which the material can be permitted to remain in themachine for any desired length of time, or can be released at intervalsor at any time deemed proper, and which includes means for supplyingliquid simultaneously to all of the compartments, or to any particularcompartment or group of compartments.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which-- Figure 1 is a sideelevation of an embodiment of my invention, having parts of thecompartment or section broken away to show the interior thereof; Fig. 2is an elevation of the discharge end of the machine; and Fig. 3 is aplan view showing the compartments or sections in broken outline, withthe partitions therein in full lines.

Before proceeding to a more detailed explanation of my invention, itshould be clearly understood that the present form of the deviceconstitutes an improvement upon the mixing machine shown in my UnitedStates Patent No. 851,553, dated April 23, 1907. The mixing machineillustrated herewith is similar in form to the patented type, consistingof two or more rectangular, preferably cube-shaped sections orcompartments, communicating interiorly, and mounted so that they can berevolved.

The improvements consist mainly, as will appear hereinafter, in thepartitions arranged within the sections, which serve to direct and guidethe material passing through the machine.

While the invention shown for example, comprises two sections orcompartments, any desired number can be employed.

Referring more particularly to the drawings, I have shown a suitablesupport-ing frame 10 of timbers or the like, and having cross beams 11provided with bearings 12 in which are journaled parallel shafts 13,only one of which is shown. One of the shafts 13 has a pulley 14;,which, together with a suitable belt 15, serves to connect the machinewith a motor or other source of power. Uprights 16 mounted upon theframe, carry the feed hopper 17 having an outlet chute 18 through whichthe material to be mixed can escape to enter the mixing machine proper.This comprises two sections or compartments A and B of rectangular formand preferably cube-shaped. The sections may be fashioned from cast orsheet metal, or from any other material adapted for the purpose. Theinlet section A has one corner cut away and provided with an inlet 19preferably circular in form and having the chute 18 of the hopper l7projecting into it, so that the material passes directly from the hopperinto the section A. The sections are inclined with respect to thehorizontal, and each has associated there with an annular rim or guide20 supported upon suitable rollers 21 carried by the shafts 13 so thatthe machine can be revolved in the usual manner. The sections A and Bare cut away at adjacent corners and are integrally or otherwisesuitably connected. I prefer to provide the sections of the present formof the device with rounded corners instead of angular-corners, as in theearlier machine. The communicating openings of the sections A and B arerectangular, and each involves approximately a quarter of each of thesurfaces forming the corner which is cut away. The lines ofintersect-ion of the cube-shaped compartments are parallel to edges ofthe compartments as is shown most clearly in Fig. 1 at a and b.

Vithin the section A is located a wall or partition 22 extendingentirely across the compartment and arranged at a slight angle with theopposite faces of the compartment between which itis located. Thepartition extends across the compartment between the inlet opening 19and the outlet opening into the compartment B, and is cut away at oneend to form an opening .23 so that material can pass through the same tothe other compartment. As a result, the com Jartment is substantiallyL-shaped-and is cut away along two lines extending at right angles fromsubstantially its center to edges, and parallel respectively to theremaining edges. The partition has an extension 24 substantiallytriangular in form and at right angles to the body of the partition. Itextends along one of the lines at which the partition is cut away and issubstantially parallel to the surfaces with which the partition is atright angles. The extension 24 is disposed toward the openings betweenthe compartments A and B. One of the sides of the compartmentA withwhich the extension 2st is parallel, is extended through the communicating openings of the compartments A and B into the compartment B toform a guiding partition 25. This partition 25 is at substantially rightangles with the partition 22 and extends over an edge of the same as isshown most clearly in Fig. 3. The partition 25 is substantiallyrectangular and has associated therewith at one end an upwardly disposedwall 26 forming a second partition within the compartment B.

A chute 27 is positioned within the compartment B and extends throughthe outlet opening 28 of the compartment. It is joined at its inner endto the wall 20, as is shown most clearly in Figs. 1 and 2. The chute hasat one side a laterally disposed flange 29 tapered from the outer end,toward the inner end of the chute. The chute, it will be understood,projects through the opening to the outside, and is preferably slightlycurved in cross section as is shown in Fig. 1. The chute is preferablyarranged at a small angle with respect to the. surfaces between which itextends, so that it is likewise at an angle with respect to thepartition 25, as is .shown in Fig. 1.

The outlet opening 28 of the compartment B is formed by cutting away onecorner of the compartment along diagonal lines 0 and cl of adjacentsurfaces and along a line f of the third surface. The sides of the linef are at an angle and are slightly curved. The escape chute 27 with itsflange 29-fits exactly against the angular edge 7.

A door 30 is provided for the outlet opening of the compartment B, andis pivoted at one side of the cube B, by means of a pin 30'. The upwardmovement of the door 30 is limited by contact with a suitable stop 31. Ialso provide a pipe 32 communicating with any suitable source of watersupply and having a bifurcated-fitting 33 so that two branch pipes 3iand 35 can be connected with the main supply pipe 32, each branch pipebeing provided with a controlling valve 36. The pipes 34 and 35 leadinto the body of the machine through the inlet opening 19, one pipeterminating within the cube A and the other within the cube B. Thepartition 22 at its center has a cutaway part 37 through which the waterpipes extend. The arrangement of the water pipes, it will be understood,is similar to that shown in my patent above referred to. The chute 27has an opening 27 for one of the pipes'.

In the operation of the machine, as the cube sections are revolved, theentering material will drop to the lowest point in 'the cube section A,tumbling from corner to corner, and will continue thus to change itsposition in the chamber until it escapes through the opening into thecompartment B. The partition 22, with the extension 24:, serves to guidethe material to the opening between the compartments. As the materialtumbles about within the compartments, it is thoroughly mixed in theusual manner. The operation is continued within the compartment B untilthe material finally fallsupon the outlet chute 27 and escapes throughthe opening 28 of the compartment B. The partitions not only serve toguide and direct the material into the machine, but also assist in themingling of the constituents thereof. The flange 29 of the outletchuteprevents the material from escaping accidentally at the side and servesto direct it 011 to a further, fixed chute 38 by means of which it canbe led to any suitable point, where it can be utilized, or from which itcan be transported elsewhere.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent:
